Study on On-line Monitoring of Deformation of Scott Transformer Winding
Zhengqing Han · 2005
Based on theoretical analysis of Scott transformer,the method of detecting the winding deformation for the Scott transformer is proposed. The method is based on on-line monitoring of primary and secondary currents and voltages to carry out real-time computation of the short-circuit reactance of windings. The simulation results show that the changes of the operation condition of transformer and the external factors will not influence the accuracy of the short-circuit reactance of windings. The method can provide veracious information of monitoring for on line operation of Scott transformer winding.
